The best audio codec is defined according to your aims: sound quality and size compression ability. Read details below.

What is the best audio format for sound quality? Which is the best quality audio format?

Best sound-quality audio formats are lossless formats. Read more about audio formats with maximal audio quality...

Which is the best sound quality?

Sound qualuty have 2 definitions:

• [objective] distortion level;
• [subjective] how it sounds - noce or not.

At the first sight, subjective definition may not be estimated. But, it wasn't.

Both definitions are united by psychoacoustics.

Does high res audio sound better?

It is matter of audio equipment and played back recording. High resolution give potential abilities to achieve better result for designers of audio equipment and software,

What is the best format for music?

Music require maximal abilities, that can provide audio formats (codecs).

Lossless file formats in high resolution are recommended, as default.

But, for portable audio players and mobile phones, high bitrates (256 kbps and higher) are recommended for stereo recording, that compressed by lossy codecs (mp3, AAC).

Is FLAC better than mp3? Is WAV better than mp3? Is FLAC or WAV better?

FLAC provide size compressing of audio information without losses. Thus it provide better sound quality than mp3.

Stereo mp3 with high bitrates (256 kbps and higher) almost may not be distinguished with FLAC by sound quality.

But mp3 have limited resolution audio (up to 48 kHz / 16 bit) that might not provide advantages of high resolution audio.

WAV file have no standard lossless compression ability. But FLAC support audio resolution, that limited 384 kHz / 32 bit.

Standard WAV file size is limited 4 Gbytes. It solved via WAV RF64 format using. But this format have compatibility limitations with software and devices.

Which lossless audio format is the best?

WAV audio format almost is not limited in supported audio resolution. High resolutions codec output consume big hard disk space. And for WAV files with size 4 GB and more WAV/RF64 format was applied.

FLAC have no size limitation, but its maximal resolution is 384 kHz / 32 bit in some implementations.

DSD files are separate branch, that can provide lesser distortions than PCM ones (WAV, FLAC, AIFF, etc.) in some hardware implementations. In other cases PCM files may sound better than DSD ones. Read more...

Is 320 kbps good sound quality? Is 256 kbps AAC is good quality?

Yes. Stereo mp3 or AAC 320 kbps is very similar to FLAC and WAV in the same audio resolution (sample rate and bit depth). General recommendation is 256 kbps or higher for stereo mp3 or AAC.

If you use AAC in higher resolutions or multichannel audio, higher bitrate may be desirable.

General advice: try different bitrates for same original recording(s). If you hear no difference with the original recording, use this bitrate.

Which is better mp3 or AAC?

AAC designers state, that AAC better accommodated psychoacoustical factors, than mp3. So AAC is more recommended.

Actually, you can compress original lossless file to mp3 and AAC at different bitrates (256 kbps and above). Compare these files with the original by your ears.

If you don't hear difference, use mp3 or AAC, according compatibility of your audio player or software.

If you prefer high resolution audio or multichannel recordings, you can use AAC instead mp3. Because last one is limited 48 kHz / 16 bit stereo.

What is the most popular audio format?

According to Google statistics (April 2019), it mp3 is the most popular format (among mp3, WAV, FLAC, ALAC, m4a, aac). Second place - m4a, WAV, AAC. ALAC and FLAC in the 3-rd position. m4a is a container for AAC and ALAC.

What the best audio file format for iTunes?

• To maximize sound quality use lossless AIFF and ALAC (*.m4a).
• Convert similar lossless audio files to mp3 and m4a and compare its sound.
• Bitrates 256 kbps and above are recommended.
  

What best audio file format for car CD player?

If car stereo supports FLAC or WAV files, these files give maximal quality.

What is the best sounding audio file format?

To achieve maximal sound quality use lossless files.

What best audio file format for mobile phones, iPhone, iPad?

If internal phone/tablet's DAC is used, lossless PCM formats are preferable.

Some external DACs support DSD.

Compare your audio player app sound for DSD and PCM lossless formats.

What best audio file format for editing?

It is lossless non-compressed PCM file formats (WAV, AIFF).

What best audio codec?

Lossless codecs (FLAC, WAV, AIFF) are preferable here. It is not matter compressed or not.

The developer of mp3 recommends to using AAC instead.

What best audio file format for website and web?

In general, it is compressed formats: mp3, m4a, ogg, flac.

What best audio format for movies?

Lossless multi-channel sound formats (Dolby TrueHD, DTS-HD Master Audio) are recommended for home music systems.

To keep hard disk space DTS support lossy compression.

Also, lossy AC3 may be used.

Lossy compression is recommended to web and portable applications.

What is highest quality audio format?

Sound quality of audio format

Audio format is data structure and coding type to store musical information.

Codec is software and/or hardware to code/encode audio format to processing and/or playback on DAC (digital-to-analog converter).

Additional information:

Original stuff (DSD or PCM modulation) from ADC (analog-to-digital converter) is coded to a format with encoder.

Restoring from the format to PCM or DSD modulation to playback at DAC is performed with a decoder.

Codec = encoder + decoder.

Some sound formats are called as 'audiophile file formats'. They provide higher sound quality, than 'non-audiophile' ones.

Sound quality is considered here as distortion level of original music stuff after storing into an audio file.

There are music file formats:

• non-compressed: WAV, FLAC, AIFF, ALAC, DSF, DFF, SACD ISO.
• lossless compressed: FLAC, APE, DTS-HD Master Audio, WavPack, DFF, SACD ISO;
• lossy compressed: mp3, AAC, MQA, DTS, OGG, others.

What is mean compressed, lossy lossless format (codec)?

Compressed mean reduced-by-size audio content. As rule, lossy compression provides size compressing better, than lossless ones, because part of audio information is lost.

The best sound quality audio recording formats are called 'lossless'. They keep audio quality without any losses (audio data of original and decoded music stuff are binary identical).

Lossless formats are capable to store original musical stuff without altering. I.e. sound quality of any lossless format (compressed or not) is identical. However, the transformation between DSD and PCM lossless audio files is lossy.

The sound quality of playback

Playback sound quality is not the same sound quality of an audio format.

Losses of audio format are only part of playback sound quality.

Playback sound quality includes distortions of:

• recording, mixing, post-production;
• format;
• playback software;
• playback hardware.

EXAMPLE:

When we upsample music, it can be played back with another distortion level of playback software and/or hardware.

Upsampling is lossy. But distortion level of playback software and/or hardware may be lesser these values for the original resolution.

So, total playback distortions after lossy upsampling may be better, than without the upsampling.

Resume: the best sound quality music formats are any lossless formats. But conversion between lossless PCM and lossless DSD is lossy. However, the conversion of format or resolution audio can give playback quality advantages (read details).

Overview of audio files

Sound formats intention

Music formats are intended for solving different issues:

• maximal sound quality providing;
• saving of hard disk space at a musical device;
• song information (metadata: album artwork, song and album name, performer, etc.) providing;
• maintenance of file compatibility with software and hardware.

Music file formats. Conversion and playback

Audio format types

• by modulation: DSD and PCM;
• by size compression: compressed and non-compressed:
  compressed files by sound quality:
  • lossless,
  • lossy.

Sound quality does not matter of used operating system (Android, iOS, Windows, Mac, Linux, others) of computer or mobile device. The quality depend on playback system settings rather, including operation system drivers.

Audio formats. Common audio file extensions

* MQA format is lossy, as far as the author know (details).

FLAC in the table means 'Free Lossless Audio Codec'. *.flac file may be used as a wrapper to other formats (MQA, as for an example).

Audio formats (codecs)

PCM formats

PCM formats (WAV, FLAC, AIFF, ALAC, APE, MQA, CD-audio) may be compressed (lossless or lossy) or not.

Most popular WAV and AIFF may have metadata compatibility issues with audio software and hardware.

Lossless audio formats

What is the best lossless audio format? By sound quality all lossless formats are identical. But there are compatibility and metadata issues. Read the details below.

Additional stuff:

WAV, AIFF

These music files are most popular among uncompressed lossless formats. Lossy compressed audio data may be stored in the *.wav and *.aiff files though.

Many sonic devices support these formats, but there aremay be issues with metadata displaying at some hardware and software.

AIFF may be recommended as an uncompressed format for iTunes due metadata compatibility.

WAV and AIFF can contain DoP packed DSD audio stream. Such files cannot be played back without special processing or hardware.

In general WAV, AIFF may be used to editing software (faster opening without additional processing), home music library at big size hard disks. For the libraries, Free Lossless Audio Codec is more recommended.

AIFF and WAV have no special limitation by sample rate and bit depth (except header field size). File size for these types is limited: 2 GBytes.

WAV RF64 and SONY's WAV64 formats allow to creating WAVs with size more 2 GBytes.

There is AIFF-C lossless format for CD-audio tracks. Read the details below.

Free Lossless Audio Codec (FLAC)

FLAC compressed lossless format reduces file size and keep binary audio content without altering. FLAC has compatibility by metadata with many hardware and software.

There are uncompressed FLAC, that some people consider as better sounding. There is a technical hypothesis: why it may be so. But currently no safe evidence. Look details here.

FLAC is not compatible with iTunes player.

Like WAV and AIFF, Free Lossless Audio Codec can contain DoP packed DSD music.

FLAC maximal resolution is 32 bit / 384 kHz and its size may be more 2 GBytes (may depend on used editing and conversion software).

Apple Lossless Audio Codec (ALAC)

It is losslessly compressed audio file format. The format may be recommended as FLAC replacement for iTunes.

CD audio

Compact disk (CD) contains data in format like WAV 16 bit / 44.1 kHz. Audio data from compact disk may be stored in WAV and other audio files via CD ripper software.

Under Windows at compact disk *.cda files are displayed. But it is index files that contain track time position. *.cda file copying doesn't provide audio stuff extracting. There is need audio ripping software.

Under Mac OSX *.aiff files are displayed at a compact disk. These files may be copied as usual sound files. But these files contain AIFF-C lossless format. It has inverse order of audio bytes, than usual AIFF. AIFF-C may be converted to AIFF without losses.

WMA lossless

WMA (Windows Media Audio) has the lossless ability at codec version 9.

The decoder WMA to WAV (wmal2pcm) may be downloaded here

APE

APE (Monkey's Audio codec) has the lossless compressing ability. Metadata are supported. Official codec builds, known by the author, for Windows only.

Read details here

WavPack

WavePack is a lossless audio format. Metadata are supported.

Read details here

CAF (lossless)

CAF (Core Audio Format) is file container for lossless audio format (uncompressed PCM or compressed by ALAC codec). Metadata are supported. Also, see CAF lossy

Read details here

Lossy compressed

mp3, aac, ogg, wma, ac3, dts and other

Lossy compressed formats like mp3, aac, ogg and others are intended to save maximal song number into limited hard disk space of musical device (especially mobile phone or portable digital audio player) or computer.

AAC more modern codec than mp3. And AAC developers promise better sound quality, than mp3 (details).

Lossy compressing technologies are balance between audio quality losses and minimal size.

Bitstream characterizes lossy files. The bitstream is bit number of audio information per second. The best bitstream audio quality (kbps / kbit per second) mean minimal file size, but still good sound quality.

As rule lossy files have no metadata compatibility issues.

WAV and AIFF have lossy modifications. But they are not widespread.

What is best audio codec for lossy file? It is unknown exactly, because depending on many factors.

In general, to provide high sound quality of mp3, 256 kbit/s and higher bitrates may be recommended.

Windows Media Audio (WMA) format is one of the popular lossy codecs, that also have lossless abilities in version 9.

ac3, aac, dts formats allow to storing multichannel compressed sound.

Additional stuff:

CAF (lossy)

CAF (Core Audio Format) is file container for lossy audio formats (compressed by AAC, mp3 and other codecs). Metadata are supported. Also, see CAF lossless

Read details here

MQA (Master Quality Authenticated)

MQA is a PCM format. Looks like, it provides better size compression than FLAC (see here). But MQA has some losses, as far as the author know (see details). Of course, MQA losses are minimal to provide high sound quality.

MQA may be played back without decoding with lesser (than MQA's maximal) sound quality. It provides its compatibility with non-MQA software and hardware.

How to choose optimal bitrate for lossy formats

The main matter of bitrate is storage space spacing. So we need to choose the minimal bitrate, that gives proper sound quality.

As rule, 256 kbit/sec and more is recommended.

But, if you want to define own optimal bitrate, here step-by-step guide:

1. Take several lossless files (FLAC, WAV, AIFF or other) as samples of your preferable musical genres.
2. Encode these samples to mp3-audio with different bitrates.
3. Compare these mp3 files with its originals by audibility of sound quality difference.
4. To future coding, you can use minimal bitrate, that causes a minimal audible difference.

DSD formats

DSF, DFF, SACD ISO (*.iso) are lossless DSD formats based on 1-bit sigma-delta modulation.

This format allows to using simplified (in concept) digital-to-analog converters, comparing PCM ones.

DFF and SACD ISO (file-image of SACD optical disk) may be DST compressed.

DSD audio content may be packed in DoP format (not compressed). DoP is stored in lossless PCM files (WAV, FLAC).

Metadata

As rule, DFF has metadata displaying issues for playback tools. SACD ISO contains text metadata only.

Stereo and multichannel

SACD ISO may contain 2 variants of single album stereo and multichannel. It causes consuming of additional space at hard disk.

To avoid the consuming SACD ISO may be extracted to DSF files with the certain channel number. As an example, for a stereo digital audio player, stereo album variant is the best option.

Also, SACD ISO file doesn't contain album artworks.

What is an audio codec

An audio codec is a program to convert original audio data stream to certain format and back. Audio codec provides bit/byte order, data headers, compression/decompression and other.

Original audio stream is a raw sequence of non-formatted digital audio data.

As rule, audio codecs are included to audio conversion software and program or hardware players.

Example of audio codec types:

mp3 codec, flac codec, aac codec, other.

Audio formats for iTunes

iTunes audio player software allows to playback both audiophile and lossy formats. But there is a limitation: iTunes don't play FLAC and DSD files. Also, iTunes can't read WAV metadata.

FLAC may be replaced to Apple Lossless Codec (ALAC with *.m4a extension).

WAV may be replaced to AIFF. However, metadata (text and artwork) should be stored in a format compatible with iTunes.

What is the best audio format? Conclusions

Lossless Converter For Itunes 1 7 0 Audio Cassette

When you choose the best audio format for the sound quality of your music library, it needs to consider:

• compatibility with used software and hardware;
• desirable sound quality (maximal for your audio system);
• desirable number songs in limited hard disk space of computer or musical device.

For audiophiles may be recommended lossless formats: DSF, FLAC, ALAC (*.m4a), WAV, AIFF, CAF files.

DFF and WAV may have metadata compatibility issues.

To saving more songs at disk it is recommended to use mp3, aac, ogg. AAC is promised as the best sounding than mp3 (see above).

Extracting of stereo tracks from SACD ISO (with stereo and 5.1 album variants)
and/or downmixing of multichannel tracks to stereo
can save hard disk space at stereo digital audio players (DAP) and mobile phones.

Operating system of computer or mobile phone doesn't impact to sound quality of played back files. It is a matter of playback system settings rather.

Is there any way to Convert FLAC to AAC Format?

The answer to this question is affirmative, but it is not quite that simple. With the assistance of an audio converter, you can simply select the source FLAC file and convert it to the AAC. Here is the catch! Do all audio converters support FLAC format? Actually, that is frustrating because the majority of them don’t support FLAC. Somehow, if you do find software after tons of searching on the Internet and you install it, it may damage the track or lower its audio quality. No, you cannot afford this certainly. Another doubt is that FLAC is lossless format whereas AAC is the lossy format. But one thing they have in common is that they both are audio formats and it is not impossible to convert any sort of format to other.

Part 2. Convert FLAC to AAC in iTunes

iTunes 10.7 and 11.0 has the feature to convert some audio formats but it does not support FLAC format. FLAC is a lossless format and Apple has their own ALAC lossless format. To convert FLAC to AAC, a tool in AppStore known as FLACTUNES exports FLAC files into iTunes. The procedure is quite interesting. It converts FLAC into ALAC and ALAC into AAC. Obviously, FLACTUNES in not free of cost and conversions from three different formats will definitely decrease the audio quality of source file. Below we take ALAC to AAC as an example to show you the procedures of converting into AAC in iTunes.

Step 1: Select Preferences and Open Import Settings

Open iTunes. From the menu bar at the top of your computer screen in case of MAC or iTunes window in case of Windows, choose iTunes > Preferences. Click the General tab, and then click Import Settings in the lower part of the window.

Step 2: Select AAC Encoder in iTunes

Click the menu next to Import Using, and then choose the encoding format that you want to convert the songs to, in this case AAC encoder. Click OK to save the settings.

Step 3: Create AAC version

Then go back to the main interface, right click on your file and you will see a create xxx version option, in the name of what you have chosen in the previous step. For example, if you chose AAC Encoder, here presents create AAC version. Click to convert to AAC, and iTunes will save all converted files.

Tips: FLAC vs AAC Lossless

FLAC is a lossless or uncompressed format which requires a lot of disk space to store but it is good because it keeps the audio quality of the source files. Many people who make archives of music prefer FLAC Audio Format and it requires software which must support FLAC. Unfortunately, most known smartphone companies don’t embed their built-in music players with FLAC format. That’s a problem because either way, you need to convert them into AAC format so that your playlist can support them. AAC is a lossy format or you can say it is compressed format because it saves a lot of disk space and if converted by a good converter, it can contain the original source track audio quality.

The Free Lossless Audio Codec (FLAC) is the most known lossless format, so it is the best option if you want to archive your music or Audio tracks. It is quite different from other formats like AIFF, WAV, ALAC, which are also lossless formats but they require a lot of disk space as they are not compressed. It's still a lossless format, which means the audio quality is still the same as the original source. Advanced Audio Coding, also known as AAC, is similar to MP3, although it's a bit more efficient, which means that you can have files that take up less space, but with the same sound quality as MP3. AAC and MP3 both are lossy formats so they don’t waste any disk space and are compressed quite like a zip file. AAC is the successor of MP3 and it is better because it somehow tries to attain the original source file audio quality.
